l Application iledfSeptember 7, 1926. Serial No. 133,942.

My inventionl relates l"to improvements in construction, and arrangement, hereinafter described and claimed. i Y

The object of I nyflinventionr is to'provide a coolerfin which the cooling 'effect is' accom'- plshed by the evaporationof w'ater,"'thel evaporation of .the 4water being hastened the passage of :air thru the water. I

A further object of vmy invention'isA to provide a de'viceof thetype described 1n which the various parts' of the device may be removed without the necessity of first uncoupling pipes, the parts when removed permitting access to the device, whereby the device may be readily cleaned.

Other objects and advantages Wlll appear in the following specification, and the novel featuresI of the invention will be particularly pointed out in the appended claims.

My invention is villustrated in the accompanying drawing, forming a part .of this application, in which-l' -r i Figure 1 is a vertical section thru the device, j "I Figure 2 is a seotionalong the lmev2-2 of Figure 1,

Figure 3 is a'section 'along'the lme of Figure 1, and .l

Figure 4 is a detailed view of the device.

In carryingoutmy inventlon, I provide a casing 1 inwhich Imount a box 2. The box 2 is slidably disposed upon guide mem` bers 3, thus permitting the box to be removed from the casing 1 at the will of the operator. Figure l3elearly shows how the front Wall of the casing 1, indicated at 4, forms a part ofthebox 2. When, therefore, the box 2 is removed from the casingl, the front Wall 4 Ais `also removed, thus permitting access to the interior of the casing.

The box 2 is kept coolv by means of evaporating water. A coil Cpipe 5 is connected to a supply pipe 6 an has its other end connected to a s ray nozzle 7. The water, in flowing thru tiie coil 5 is partially cooled,

due to the fact that the coil 5 is disposedv within the casing 1.

The water, when sprayed from the spray nozzle 7, falls upon a baie plate 8, and from this point, the water drops upon a lsecond baie plate 9 and a third baiile plate 10.

These plates thin the water out into a thin film, thus causing the water to more quickly evaporate and thus produce a greater cooling effect.

' The batiie plate '10 is disposed directly above the box 2v and it will be seen from Figure `1 that' the water Vfrom the baille plate 10 would drop on top `of the box 2. The box 2 is spaced from the wall of the casing 1 onthree sides thereof (see Figure 3) and the Water will, therefore, How 'over a series of baile 'plates 11, carried by =the box 2,'and 12, carried by the casing 1. The water, in dropping'v from baie to baflie, provides a thin film, thru which air is forced, thus causing the water to quickly evaporate andlcool the temperature within the casmg.

g 'The water drops from the baies 11 and 12 into a reservoir 13, this reservoir being in the shape of a drawer Whicli'may be removed from the casing'l in a manner hereinafter described. The water passes from the reservoir 13 thru an overfiow pipe 14 and into an exhaust pipe 15. If desired, a valve 16 may be closedl and a valve 17 opened for directi ingl the water: into a pump 18. A pipe 19 leads from the pump 18 and connects with a pipe 20 which'eommunicates with the coil 5. A valve 21 controls the fiow of water from the pipe 20 into the coil 5. When the valves 16 and 22 are closed, and the valves 17 and 21, are open, water will be drawn-from the reservoir 13 and forced back into the'coil 5. In this way, the same water is used time after time for evaporating the smaller portion thereof for cooling the'box 2.

The air for causing the evaporation of the water is admitted thru the inletpipe 23 and the flow of air is controlled by a damper 24. From the pipe 23, the air passes thru a conduit 25, a pipe 26, a pipe 27, and into a compartment 28. From here, the air is forced into a compartment 29 by means of a fan 30. The fan forces the air from the compartment 29 thru va pipe 31, a pipe 32, and an air ejector 33. It will be noted that the air will oe forced thru the thin films of water dropping from each baile plate and in this way the water is caused to be evaporated very quickly,l thus effectually cooling the box 2.

The conduit 25 opens into the upper part of the casing 1 and this openingr is controlled by a damper 34.

I have shown the top of the casing 1 as communicating with the pipe 35 and a second pipe 36. These pipes are closed by means of dampers 37 and 38. The pipe 35 may lead to the interior of a house for cool- In Figure 4, I show a pipe 39 as comLA nmnicating with the interior-.of the box 2 and with the eonduit'25. This pipe 1s for .the purpose of withdrawing odors from the box. flow of airtlrru the pi e 39 is controlled by means of a plugO aving openings 4l therein. A turningof the plug. v40 will enlar e or decreasethe size of the openL ing and ius ldetermine thefamount ,ofair forced thruthe pipe 39. I ne' -o f the principal features of the inT vention isL thatlhebox 2 may be. removed, thefreservoir 1.3 may ..be removed, and the drawer 42 containingthe motor may be removed without the necessityof first disconnecting'ja number ofpipes. To accomplish this, I have shown the pipe 2G as hav:- ing a friction fityvith the pipe 27, the pipe 3l lnvingga friction lit with the drawer and tie pipeA 32,. and the pipe 14 ,having va friction fit with the reseryoir 1 3. This construction permits the drawer 42 -and the reservoir 13 to be removed from the casing L Mnencver desired.. A mere movement 'of thesefmeinbers back into positionwill autoJ matically-connect the .various pipes. together. Inililce',V mannerfthe pipe 39 hasfa friction connection .with .the conduit 25.and no vyv permits, the'box-2 to-.beicmoyed from thel eas in g1 whenever desired without lthe 'necessity offlirst disconmeeting the pipe .39 -fjrom-the conduit25. i

,From .the foregoing description/of. the various parts of the --device, theoperation thereof may be.readilynnderstood. I have already described how the coolin-gof theboxf 2 is accomplished bymeans ofthe` water and `th e,.forcing of fthe .air `thru the' water. The

same water may be used time after timeif so desired. I have further set forth how the water maybe exhausted 'and the aireithei` led into the house or exhausted. Thedevice is also adaptedto remove odors from the ice box@ j -l The entire device is especially constructed for permitting the box, the drawer, and the reservoir to be removed from the casing l. In this manner, the casing may `be cleaned at will.
